Unfortunate that 303 is the name of the company. Makes it
a bit misleading when choosing a product. Not sure about the
5 years or less part. Normally one should not need to waterproof
canvas that is less that 5 years old unless it has been abused.
Sunbrella is guaranteed for 5 years so if it leaks prior to that
age, you are theoretically entitled to some compensation.
But once you start using a treatment, you have to keep up with it,
normally at least once a year. Time to get new canvas.

Yes, and it works well on canvas that's 5 years old or less. It's based on
Teflon, and for me, didn't work well on older canvas. Be sure you get the
303 waterproofing for canvas, NOT the 303 for fiberglass and hard
surfaces!
Don't ask me how I know this.

Wash the canvas first with a really mild soap solution. Best is to shave
off
some ivory soap bars. The ivory snow flakes will work well too, but
they're
not just straight soap like they used to be.

Our dodger is getting a bit porous and I have heard that 303 is the way
to
go.
Anybody use the stuff?
Results?
